TCNOISE: A Computer Program to Calculate Noise Levels and Directivity from a Jet Engine Test Cell

C. A. Kodres, Timothy W. Lancey

Open publisher page 0 citations

Abstract

Abstract : This report presents the Fortran program TCNOISE (Test Cell NOISE). The program predicts noise emitted by jet engine test cells. It is to be used in conjunction with the Naval Facilities Engineering Service Center's jet engine test cell aerothermal performance computer model, reading output files from this code to acquire the flow properties necessary for the calculation of jet noise and surface noise. The theoretical basis of TCNOISE, instructions for running the program, example runs, and comparisons of program predictions with measured noise emissions are included in the report.
